3/4 ton rear axle

[Impact02]

I have a 3/4 ton trailing arm rear axel in a truck I am taking some parts off of. Is there much need for one or just scrap it with the rest of the truck.

[wrangler94]

if it's an Eaton HO52 do not scrap it. round covers, resembles a ford 9 inch rear end? do not scrap it. either save it or sell it. if you only sell it for 25 dollars don't scrap it. people in the jeep world and stuff would love to have it. I'd love to have it. I have no use for it but i've bought one before just to keep it from the junk yard.

[wrangler94]

if you're going to scrap it I will figure out how to work it in my schedule to drive to ohio and pick it up if it keeps you from scrapping it.

Yep -- it is.

[wrangler94]

again, don't scrap it. please. they don't make them any more, and alot of "modern" 14 bolt stuff, which isn't new any more either, will go in it. is anything else on the truck worth saving? pics of whole truck? as I said I'll figure out how to work it in somehow to go pick the thing up if it's just gonna get crushed.

[Impact02]

Not much worth saving. A few little things has sat in the woods for around 30 years. I am pulling anything worth saving.

[wrangler94]

PM me or whatever. if i don't come get it, there are guys I know in your area that likely would just to save the axle. Yeah i see what you mean about the rest of the truck maybe not worth saving.

[jumpsoffrock]

That poor truck. If it isn't too much trouble, maybe post some more pics inside and out just for the fun of it.....lord almighty that truck is in rough shape.

[Wrenchbender Ret]

I wonder how the truck is equipped. That could be a 4:11 ratio.

yours might be a HO 72, if it had the preload bolt for the pinion.

[Impact02]

The steering box is not even worth saving. I think the only options were gauges and a 350. Can’t read spid cut the dash out to hang on the garage wall. Is this the pre load bolt.

All HO 72s had the pinion preload bolt...... for reasons unknown to me, some HO 52s had it, and some did not. Maybe it depends on the model year?

In case anyone is not aware, one-ton trucks had HO 72 differentials, and 3/4 tons (C/K20) had HO 52 diffs.

Yes, it is. You have a C20 with an Eaton HO 52 with a pinion preload bolt.

Ok I'm going to clarify somethings with Hos it depends on the GVW from what I have seen. I had a GM manual stating this. HO 72s came in 7200 gvw vehicles. Which some C20s where available with that the extra heavy duty especially. The HO 52 came in 5200 gvw c20 trucks and all 4x4 k20s because the k20s highest gvw was 5200 because the frames where basically the same as 1/2 ton frames with 3/4 ton parts. Your one ton dually had h110 rear axel. So I'd check the GVW since I see the load bolt it might be a HO 72.

[Impact02]

I don’t know much about this axel I am learning. The only thing I have around my house is the 14 bolt full floaters. From the 80’s. Here’s the tag I am sure you know more than me about this axel.

That’s not true on the GVW numbers. Data plate from my K20. The frame is the same as a 1/2 ton long bed is but the GVW is higher on the K20, factory tire options had a bit to do with it as well. Also I’m not sure about the 7200 gvw/HO72 being true either, as far as I know the HO72’s are a 1ton thing, along with the 110. I’ve never seen a 7500 lb K20 have a 72, I’ve never seen a k with a 72 period.

If it's a C/20 it's an HO52. Some HO52s had the preload bolt as well. HO72s came in C/30s and the difference is in the brakes

[Stocker]

Thanks for the added info, guys. I knew there was some difference but couldn't remember if it was brakes, bearings, or something else.
